All instructions provided in the Yahoo APIs and their associated documentation on the Yahoo Developer Network to place application identification information (API Key) into any application or service you develop that incorporates or makes any use of the Yahoo APIs. You may only create a single API Key per application or service and such API Key must accompany all web services requests coming from that application or service. You can sign up for an API Key at http://developer.yahoo.com/wsregapp/ for BBAuth API Keys and at http://developer.yahoo.com/dashboard/createKey.html for OAuth API Keys. You must provide accurate identification, contact, and other information required as part of the registration process. You SHALL NOT create any script or other automated tool that attempts to create multiple API Keys.
You represent and warrant to Yahoo that: (a) you have the right to use, reproduce, transmit, copy, publicly display, publicly perform, and distribute any content in or made available to Yahoo and Yahoo users by your use of the Yahoo APIs in the manner contemplated under this Agreement, and that use by Yahoo or others of any such content via the Yahoo web service or API shall not violate the rights of any third party (e.g., copyright, patent, trademark, or other proprietary right of any person or entity), or any applicable regulation or law, including but not limited to any export, re-export, or import laws and the laws of any country in which your content or service is made available; and (b) if you submit or permit the submission of your or your users’ content or activity through or into a Yahoo web service or API, you also grant the following perpetual, non-exclusive license to, use of, and rights to your or your users’ content or activity to others (such “others” may include but are not limited to Yahoo users): (i) to access, distribute and/or display your or your users’ content or activity; (ii) the ability for Yahoo registered users to rate, review, comment on and tag Your Content; and (iii) the ability to access, reproduce, distribute and/or perform your or your users’ content, activity, or information via Yahoo’s web service APIs or via RSS or any similar XML or related feeds both on and off Yahoo-controlled web sites.

You understand that the Yahoo APIs are not designed for such purposes and that their failure in such cases could lead to death, personal injury, or severe property or environmental damage for which Yahoo is not responsible;
Sell, lease, share, transfer, or sublicense the Yahoo APIs or access or access codes thereto or derive income from the use or provision of the Yahoo APIs, whether for direct commercial or monetary gain or otherwise, unless the API Documents specifically permit otherwise or Yahoo gives prior, express, written permission; or

Collect from the Yahoo APIs, or use or disclose if obtained from the Yahoo APIs, or write to the Yahoo APIs, any Yahoo user data, personal information as defined by the Children's Online Privacy Protection Act, or other information associated with users under age 13.
OAuth and Brower-Based Authentication (“BBAuth”). If your use of Yahoo APIs will access Yahoo user information, or read or write information from or to Yahoo user accounts through Yahoo APIs, you must use either OAuth (http://developer.yahoo.com/oauth) or BBAuth (http://developer.yahoo.com/auth to authenticate your access to the Yahoo network. The terms of this Section 1(h) applies to your use of OAuth and BBAuth.
Yahoo takes end user security and privacy very seriously, and you agree to give us all necessary assistance for the operation of your Application in compliance with these TOU and any applicable laws.
Securing User Consent. You are solely responsible for securing clear, express consent from the user, granting you permission to access such user’s Yahoo account using OAuth-enabled APIs or BBAuth-enabled APIs, including if applicable, retrieving user-specific information, or writing information to such user’s account. You will strictly comply with the scope of express consent they granted you when accessing such user’s Yahoo account.
Contact and Cooperation. You (or the name of the contact you gave to Yahoo when you applied for your API Key for review if it's not you) must be reachable at all times for security questions or concerns. You can change this name or contact by signing up for a new API Key, and providing the correct contact information and using the new API Key instead. (http://developer.yahoo.com/wsregapp/ for BBAuth API Keys and http://developer.yahoo.com/dashboard/createKey.html for OAuth API Keys).
Virus Precautions. All materials, including software and documents, that you provide to Yahoo, must be checked with Internet industry standard up-to-date antivirus and anti-worm software, and determined to be virus-free and worm-free. Any data provided to Yahoo must not contain harmful scripts or code.
Industry Standards. Your networks, operating system and software of its web server(s), routers, databases, and computer systems (collectively, “System” or “Systems”) must be properly configured to Internet industry standards, as required to securely operate your Application. If you do not completely control any aspect of the System you will use all control or influence that you have over such Systems, and you will not architect or select Systems in a manner to avoid the foregoing obligation. An example of an unacceptable server is one that operates as open proxy. An example of architecting in an unacceptable manner would be if you select a server operated by a vendor with substandard security practices, so that you could contend that you do not control such server, in order to avoid having to select an acceptable server.
Reporting. You must promptly report any security deficiencies in or intrusions to your Systems that you discover to Yahoo in writing via email to firstname.lastname@example.org . You will work with Yahoo to immediately correct any security deficiency, and will disconnect immediately any intrusions or intruder. In the event of any such security deficiency or intrusion, you will make no public statements (i.e. press, blogs, bulletin boards, etc.) without prior written and express permission from Yahoo in each instance.
Access Control to Systems. To the extent you have control or influence over the Systems, you will log (in a time and date-stamped fashion) all instances of access to the Systems. you will encrypt the password and username files for the Systems that store or process any Yahoo user data that you are permitted by Yahoo to access. Passwords must be unique, unintuitive, and changed often. You will minimize access to and use of the passwords. Wherever possible, commands which require additional privileges should be securely logged (with time and date) to enable a complete audit trail of activities. When an individual terminates his or her employment with you, his or her passwords and access password facilities must be terminated immediately.
Security Reviews. Yahoo will have the right, at its own expense, to review, or to have an independent third party that is not your competitor, to inspect and review your compliance with these security provisions. You will (at your own expense) correct any security flaws detected by such a review as soon as possible. You will then promptly certify to Yahoo in writing that the security flaw has been corrected, along with a description of the corrective action(s) taken. Yahoo will give you 48 hours notice before conducting such a review, and may conduct no more than four reviews annually. Any such review will be conducted during regular business hours in such a manner as not to interfere with normal business activities. If a review reveals a material breach of any of these security provisions, you will reimburse Yahoo for the reasonable costs of the review.
Data Collection, Storage, and Use.
You may not retain or use, and must immediately remove from any Application and any data repository in your possession or under your control any Yahoo user data obtained through the Yahoo APIs not explicitly identified as being storable indefinitely in the API Documents within 24 hours after the time at which you obtained the data, or such other time as Yahoo may specify to you from time to time, including pursuant to notification received from application uninstall event handlers.
You may not share GUIDs (Global Unique Identifiers) with any third party.
Yahoo may elect to provide you with support or modifications for the Yahoo APIs (collectively, "Support"), in its sole discretion, and may terminate such Support at any time without notice to you. Yahoo may change, suspend, or discontinue any aspect of the Yahoo APIs at any time, including the availability of any Yahoo APIs. Yahoo may also impose limits on certain features and services or restrict your access to parts or all of the Yahoo APIs or the Yahoo Web site without notice or liability.
